So On the first connection to derby I must create in the
derby.system.home a derby.properties that tell's it to change its
derby.system.home to dir, so that there it finds another
derby.properties with the properties I want? And I must do that for
every connection/boot.
The idea is that I don't want to write in the user working directory
(the default for derby.system.home) any .properties or .log file, but
rather in my dir.
How would you achieve this?
